GAN-FILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 315,622, dated Aprille, 1885.

Application filed August 13, 1S4. i (No model.)

To @ZZ whom it may concern:

Be it known that I, JOHN G. Hosrinx's, of Baltimore city, Maryland, haveinvented certain new and useful Improvements in Can- Filling Machines,oi'v which the following is a speciiication, reference being had to theaccompanying drawings, forming part hereof, in which- Figure 1 is a viewin side elevationpartly broken away. Fig. 21s a top plan View. Fig. 3 isa partial rear elevation, parts being omitted; and Fig. 4 is a partialsection on a plane from front to rear.

Like letters mark the same parts in all the figures.

My invention relates to machines for filling cans (prior to hermeticallysealing them) with fruits, vegetables, thc., the construction here shownbeing especially intended for tomatoes, although it is applicable toother vegetables and fruits without change.

The object of my inventionis to furnish a machine of this class whichwill automatically carry up the cans, bring them under the fillers, putin a predetermined quantity in each can, and then automatically deliverthe filled cans, the number of cans to be filled at each stroke beingonly dependent upon the number of plungers, the machine here shown beingconstructed so that two cans are fed forward, lled, and delivered'ateach stroke.

My invention consists in the construction, arrangement, and combinationof parts,which will be iirst fully described herein, and afterwardspecifically pointed out in the claims.

Referring to the drawings by letter, A is the frame of the machine,whichconsists of standards c c a?, the standards a. being at the rear andsupporting the rear end of an inclined trough, B,which serves as ahopper and chute to deliver the mass with which the cans are to be lledto the fillers. The standards a a extend across the front of themachine, and serve to support the working parts of the machine. Thestandards a a are in the nature of crossbeains, and to one of them isattached the standard (lj-,whose upper end is embraced and supported bythe extended ends of the trough B. A standard, as, is set up at a shortdistance from the standard a2, and a shaft, C, is mounted in saidstandard c3, and extends through one of the standards a. The shaft Ccarries fast and loose pulleys c c', by means of wheel, d, on a shaft,D, passing through bearings in standards a? and a. On the shaft D isalso a bevel-gear, d', which enga-ges a bevelgear, e', on an uprightshaft. E. mounted in bearings e, attached to standard ai. 0n the upperend of the shaft E is another bevel-gear, which engages a bevel geanfonashat't, F, mounted in the upper end of the standard a2. This shaft Fcarries an arm, f, on which is adjustably secured a weight, j", whichserves to counterbalance a crank, f, and its attachments. A pitman, g,is attached to said crank, and has secured to its lower end across head,g', which slides up and down, carrying with it two plungers, G, whichare guided in bearings h in a bracket, H, attached to the stand ard a?.Each of these plungers carries at its bottom a head, I', located in eachof two standpipes or tubes, I, which are provided on one of their sideswith openings i, communicating with the trough B, and are funnel-shapedatl their lower ends to register with and set over the cans when inposition to be filled.

On the shaft D, inside the standard a', is mounted a square boX, J,inside of which works` an eccentric or cam, which serves to raise a rod,j, which is guided in a bearing,j, on a bracket, jg, secured to standarda. The rod j forks at its upper end, and serves, at a predeterminedtime, to raise a hinged plate, K, which forms thus a movable bottom tothe lower end of the trough and to more effectually dump the mass intothe tubes I. This plate K is formed with an angular projecting end, k,which, when the plate is raised,serves to prevent any further iiow ofmaterial down the trough to the tubes I, and to prevent leakage from thetrough.

On the inner end of the shaft D is a faceplate, Ii, having a slot, Z, inwhich is adjustably secured a crank-pin, Z', which carries a lever orpitman, Z2, whose outer end connects with a lever, M, pivoted centrallyon a shaft, N, mounted in suitable bearings near one end (which we maycall the rear end) of the standards a.

Onthe pin ml, which connects the pitman Z2 and lever M, is also hung agravity-pawl, mx,

which engages agear-wheel m mounted on the shaft N, which gear-wheel inturn engages 'a pinion, p, mounted on a shaft, P, which works insuitable bearings at the rear end of the standards a. The pitman Z2 isprovided with an adjustable joint,-`Z3, by means of which it may beadjusted in length, when desired. A shaft, P', is mounted in suitablebearings at the opposite end of standards a', and on the shafts P andP', between the standards LQ-are secured square blocks O and O', eachside of the block O being provided with a block, O2, shaped as a segmentof a circle, which serve as teeth to engage and draw forward an endlessbelt composed of fiat square links R, each link having a circularperforation in which to place a can, the cans resting throug'nsaidperforations on a board or table,vS, over which the chain moves. l x

The mass of material beingv placed in thel trough, the parts being inposition,a's inFig'. 1, motion is communicated and thefoll'owing`operations performed, viz: vlhe'forked rod j, raised by the camin box J,pushes'up thehin'ged plate K, dumping a portion of thecont'e'nts ofl thetrough into the .filling-tubes. The plungers now descend, closing uptheopeningsfin the tubes and forcing the oontentsof` the'tubes into thecans below. Next the p-lungers ascend ready for another stroke. ln'thelmeanwhile the endless belt has beencar'r'i'ed forward the space of twolinks, bringing two more cans'under the tubes and carrying away the twoalreadyfilled. The plate K again ,dumps and; the operations arerepeated. The motionsa're all effected from the main'shaft,andarepropThe pitman' Z2 `can be given a longer or shorter throw by adjusting itscrank or wrist pin in thesl'otin the face-plate. The plungers can beadjusted' on the cross-head, the weight on the cou'rite'rbalf ance-armmay be adjusted, and the length of the tubes may be altered to suit thethrow of the plungers by the telescopic arrangement .shown in Fig. 3.The trough has Ya` Slatted bottom to drain thc liquid out ofthe contentsthereof. The bottom of pipes' I maybe made -into funnels I2, removableor fixed, as desired.

A suitable drain-pipe, B, attached to ylower side of trough B, carriesoff waste liquor into any suitable receptacle to be thrown away orutilized, as desired, a slat bottom, B2, draining off the liquor in thetrough.

Having thus described my' invention, what I v claim, and desire tosecure by Letters Patent j l. The combination, with the tubes havingopenings in their sides, of the trough ending at said openings, andhaving its lower end arranged to dump a quantity of the contents of 6o4. In combination, the trough, thepivoted pla-te K, the tubes I, withopenings t', and the plunger's, as set forth.

5.' In combination, the trough B, tubes I,

plungers I, rods G, crossh`ead y', pitman g, and crank f3, as set forth.v

6. In combination, the tubes I, the endless belt composed of linksR,ihaving circular open'- ing's, and the blocks O O', as set forth.

7. The endless belt composed of links B,hav ing circular openings, incombinationV with blocks O'and 0, the block-O having segments O2 toengage said openings and serve as teeth,

the openings also serving as can-receptacles, as set forth.

8. In combination, the trough B, hinged plate K, tubes I, with openingst', the forked rod j, and mechanism to raise it periodically tocorrespond with the movement of the end'- less belt which carries thecans, asset forth.
